Even though LeBron James is nearing his 33rd birthday, Tyronn Lue believes he is aging in reverse.

"He seems younger," Lue said following Cleveland's first practice of the season Tuesday. "I call him 'Benjamin Button.' He seems younger, he just seems happier with the game right now, just having fun. Enjoying the game. Hopefully it carries on for 82 games and into the playoffs."

James is attempting to reach The Finals for his eighth straight season.

"I'm ready to go," James said at the Cavs' media day on Monday. "This is one of the best offseasons I've had in my career. And I'm extremely excited. What got me excited about the game of basketball is actually being with my sons this summer and watching their AAU games and you probably saw a couple videos where I was not a nice dad during the course of those games. But the 'Basketball Jones' and the basketball fever was put back in me early in July, and it's crazy to say that my 12-year-old and my 10-year-old can inspire me and they did, and their teammates inspired me to get in the gym. I always get better throughout the offseason. I always work on my game or work on my body throughout the offseason."

Lue joked he will rely on James even more heavily this season.

"I'll probably add a minute to his minutes," Lue said with a smile. "So, 38 and a half (minutes per game). ... We'll see."
